mediatek: add stock layout for CMCC A10

Browse Source 
This board is also as known as SuperElectron ZN-M5 and ZN-M8. However,
for ZN-M5 and ZN-M8, there's another version uses ZX279128 as CPU
chip, which is unsupported.
You can check it in "高级设置" > "系统日志" > "内核日志" page from webUI.

Stock layout flash instructions:
Login into webUI and upload sysupgrade firmware in "系统管理" > "升级固件" page.
Remember to unselect "保留配置" ("Keep configurations") first before doing that.

OpenWrt U-Boot layout flash instructions:
1. Flash stock layout firmware first.
2. Connect to the device via SSH, and backup everything,
   especially 'Factory' partition.
3. Unlock MTD partitions:
   apk update && apk add kmod-mtd-rw
   insmod mtd-rw i_want_a_brick=1
4. Write new BL2 and FIP:
   mtd write immortalwrt-mediatek-filogic-cmcc_a10-ubootmod-preloader.bin BL2
   mtd write immortalwrt-mediatek-filogic-cmcc_a10-ubootmod-bl31-uboot.fip FIP
5. Set static IP on your PC:
   IP 192.168.1.254/24, GW 192.168.1.1
6. Serve ImmortalWrt initramfs image using TFTP server.
7. Cut off the power and re-engage, wait for TFTP recovery to complete.
8. After ImmortalWrt has booted, perform sysupgrade.
